Export Contacts

I guess sometimes you will have wanted to export your contacts outside of the phone to the SIM change you, or for another reason. Until now, Google gives the option to do this, and is a very good system. But the question is what is necessary to use only the google system, do I have to continue to provide personal information to that company?. ExportContacts, offers you a system as good as any, to export-import your contacts. Exports by private means (e-mail or FTP), all in a ZIP compressed.
